DETAILED DESCRIPTION

The present disclosure relates to a lighting system, a lightingapparatus, and a lighting control method, and more particularly, to alighting control method of controlling a lighting apparatus based on amotion or touch of an input device and/or providing a lighting effectsimilar to a focused or input image based on data of the image, alighting system, and a lighting apparatus.

A conventional lighting system, which uses light sources, such as anincandescent lamp, a discharge lamp, and a fluorescent lamp, has beenused for house, decoration, and industry. Of the above light sources,the incandescent lamp, which is a resistive light source, has lowefficiency and generates a large amount of heat, the discharge lamp isvery expensive and requires a high voltage, and the fluorescent lampcauses environmental pollution due to its use of mercury.

A lighting emitting diode (LED) may provide advantages in efficiency,various color reproduction, and unlimited design. The lighting emittingdiode is a semiconductor device that emits light when forward voltage isapplied. The lighting emitting diode has electrical, optical, andphysical properties in which lighting emitting diode has a long lifespanand low power consumption, and is suitable for mass production. Byvirtue of these properties, the above conventional light sources havebeen rapidly replaced by the lighting emitting diode.

In a large-sized building or a house, however, the light apparatus iscontrolled only through a program switch or a dedicated control meansfor the light apparatus, which may be inconvenient to use. Also, thelight apparatus has limits in expressing or reproducing colors orsetting lighting schemes, such as reproducing a color of the sky,sunset, sunrise, or simply being capable of reproducing a color schemedesired by the user.

Accordingly, the present disclosure is directed to a lighting system, alighting apparatus, a lighting control device and a method ofcontrolling the same that substantially obviate one or more problems dueto limitations and disadvantages of the related art.

An object of the present disclosure is to control a lighting apparatusconnected via a wired/wireless network using an available peripheralinput device in addition to a predetermined control means.

Another object of the present disclosure is to easily and convenientlycontrol the lighting apparatus through a motion or touch of the inputdevice without performing several complex processes.

Another object of the present disclosure is to provide a feedbackaccording to a control command during controlling of the lightingapparatus through the input device, thereby improving user's conveniencein lighting control.

Another object of the present disclosure is to control the lightingapparatus based on an image focused or input through the input devicesuch that the lighting apparatus has lighting effects identical orsimilar to the image.

Another object of the present disclosure is to control dimming, colortemperature, and color sense (e.g., color) of the lighting apparatusaccording to request or intention of a user through the input device,thereby improving user's satisfaction and marketability.

A further object of the present disclosure is to provide a lightingsystem including the input device and the lighting apparatus.

Additional advantages, objects, and features of the disclosure will beset forth in part in the description which follows and in part willbecome apparent to those having ordinary skill in the art uponexamination of the following or may be learned from practice of thedisclosure. The objectives and other advantages of the disclosure may berealized and attained by the structure particularly pointed out in thewritten description and claims hereof as well as the appended drawings.

Reference will now be made in detail to various embodiments of alighting system, a lighting apparatus, and a lighting control method,examples of which are illustrated in the accompanying drawings. Itshould be noted herein that these embodiments are for illustrativepurposes only and the technical idea of the disclosure is not limitedthereto.

The ordinal numbers areused only to distinguish between the elements.

In this specification, a “lighting control device” is intended toinclude all control means connected to a lighting system (or a lightingapparatus) via a wired/wireless network to control the lighting system(or the lighting apparatus). For example, the lighting control devicemay include a standing device, such as a digital television and apersonal computer (PC), and a mobile device, such as a smart phone, atablet PC, and a laptop computer. In addition, the lighting controldevice may also include a dedicated control means, such as acommissioning tool, for the lighting system or the lighting apparatus.Hereinafter, a mobile device will be described as an example of thelighting control device simply for the sake of convenience.

In this specification, meanwhile, the lighting apparatus may be alighting system or a lighting unit, such as a lighting emitting device(LED), according to circumstances. Meanwhile, the wired/wireless networkis a network for connection between digital devices using variouscommunication specifications. The wired/wireless network may be formedaccording to communication specifications for wired connection, such asUniversal Serial Bus (USB), Composite Video Banking Sync (CVBS),Component, S-Video (Analog), Digital Visual Interface (DVI), HighDefinition Multimedia Interface (HDMI), RGB, and D-SUB, or communicationspecifications for wired connection, such as Bluetooth, Radio FrequencyIdentification (RFID), infrared Data Association (IrDA), Ultra Wideband(UWB), ZigBee, Digital Living Network Alliance (DLNA), Wireless LAN(WLAN)(Wi-Fi), Wireless broadband (Wibro), World Interoperability forMicrowave Access (Wimax), High Speed Downlink Packet Access (HSDPA),Long Term Evolution (LTE), and Wi-Fi Direct.

Also, a ‘motion’ as used in this specification includes change of astate, such as action, with respect to the lighting control device. Sucha state change may include all inputs to control the lighting apparatusbased on user's intention according to movement through the comparisonbetween the current state and the previous state. User's action includesall inputs to request the lighting apparatus to perform a specificfunction or operation, for example, due to a tilt (or angle), direction,and position different from those of the previous state. The statechange may be performed by users' physical pressure or force. Meanwhile,the motion may include various operations, such as shaking, up/down, androll left/roll right. The motion may be referred to as a gesture.

In addition, a ‘color sense’ as used in this specification may includevarious parameters regarding lighting effects provided by the lightingapparatus. The color sense may include more than merely color of thelight source, and may be combined, for example, with various parametersused when the lighting apparatus provides lighting effects, such asdimming and color temperature.

Meanwhile, a mobile device is described as an example of the lightingcontrol device in this specification. Consequently, it is necessary tobasically perform pairing between the lighting apparatus and thelighting control device via a wired/wireless network. To this end, thelighting control device may be directly paired with lighting apparatususing a communication protocol supported in the network. Alternatively,the lighting control device may be indirectly paired with the lightingapparatus using at least one other digital device. Meanwhile, thelighting control device may be provided with firmware or software, suchas an application, or such firmware or software may be downloaded to thelighting control device such that the firmware or software can be usedwhen the lighting control device controls the lighting apparatus.

Hereinafter, simply for ease of discussion, the lighting apparatus willbe described as being controlled through a lighting control applicationprovided by the lighting control device. In this case, it is possiblefor the lighting control device to provide information regarding colorsenses in various modes to the lighting apparatus or to request thelighting apparatus to realize such color senses. Meanwhile, a user mayprovide an image acquired using a digital camera or a PC, a focusedimage, or color sense data to the lighting apparatus through thelighting control device such that the image or the color sense data canbe realized by the lighting apparatus. The lighting apparatus may storethe input image or the color sense data (lighting scheme) for futureuse. Generation or processing of the color sense data may be performedby the lighting control device and/or the lighting apparatus.

In a case in which the user requests the lighting apparatus to reproduceor realize various colors through the lighting control device asdescribed above, control based on the motion or touch input of thelighting control device as described above is also possible. Forexample, in a case in which the user requests the lighting apparatus toreproduce a color corresponding to a specific image through the lightingcontrol device but is not satisfied with the result, it is possible tofurther control chromaticity and concentration of the color through aninput at the lighting control device, for example, through a touchinput, motion inputs at the lighting control device or anotherappropriate type of input.

Meanwhile, in this specification, anembodiment of the lighting control device 510 is a mobile device.Although not shown, the lighting control device 510 may further includeother components based on characteristics of the mobile device.

The touch unit 520 may apply a gradation of m points×n points (where, nand m indicate positive integers) and generate point informationregarding a portion touched by a user.

The touch unit 520 may refer to coordinate information based onrectangular coordinates, for example, to generate touch pointinformation and generate each piece of touch point information even whena drag is performed after a first touch or continuous touches areperformed. In a case in which the drag is performed, the touch unit 520may generate only information regarding the first touched point and thetouch point on a region at which the drag is finished as touch pointinformation and transmit the generated touch point information. On theother hand, in a case in which a plurality of pieces of touch pointinformation exists including a case in which the drag is performed,touch direction information may also be transmitted. The touch directioninformation may be information to distinguish between, for example, anup and down direction, a left and right direction, and a diagonaldirection.

The touch unit 520 may be differently operated according to the numberof the generated point information. For example, in a case in which onlya piece of point information exists, the touch unit 520 is sufficient totransmit coordinate information regarding the corresponding touch point.On the other hand, in a case in which a plurality of pieces of pointinformation exists, the touch unit 520 may transmit at least one ofcoordinate information, direction information, information regardingpositional differences between the respective pouch points, or the like.

In particular, the touch unit 520 may generate and transmit one or morecontrol data in addition to the point information based on the directioninformation. For example, if the direction information indicates an upand down direction, the touch unit 520 may transmit dimming controlinformation. If the direction information indicates a left and rightdirection, the touch unit 520 may transmit color temperature controlinformation. If the direction information indicates a diagonaldirection, the touch unit 520 may calculate point differences in the upand down direction and the left and right direction based on therectangular coordinates and transmit information that is capable ofsimultaneously controlling dimming and color temperature.

The touch unit 520 may refer to coordinate information based onrectangular coordinates, for example, to generate touch pointinformation, generate each piece of touch point information even when adrag is performed after a first touch or continuous touches areperformed, and transmit the generated touch point information to thecontroller 530.

In a case in which the drag is performed, the touch unit 520 maygenerate, for example, only information regarding the first touchedpoint and the touch point on a region at which the drag is finished astouch point information and transmit the generated touch pointinformation.

On the other hand, in a case in which a plurality of pieces of touchpoint information exist including a case in which the drag is performed,direction information based on the rectangular coordinates may betransmitted. The direction information may be information to distinguishbetween an up and down direction, a left and right direction, and adiagonal direction.

In addition, in a case in which only a piece of generated pointinformation exists, the touch unit 520 may only transmit coordinateinformation. On the other hand, in a case in which a plurality of piecesof point information is generated, the touch unit 520 may transmitinformation regarding differences between the respective touch pointstogether with coordinate information. Also, in a case in which thedirection information is a diagonal direction, the touch unit 520 mayindividually transmit point differences in the up and down direction andthe left and right direction based on the rectangular coordinates.Meanwhile, the touch unit 520 may extract pixel or dot informationcorresponding to user selection of pixels or dots and transmit theextracted pixel or dot information to the controller 530. In this case,the touch unit 520 may extract color sense data from the pixel or dotselected according to the request of the controller 520 or as defaultand transmit the extracted color sense data to the controller 530.

The controller 530 may be a 2.4 GHz ZigBee wireless communicationtransceiver system on chip (SoC) having IEEE 802.15.4 MAC/PHY embeddedtherein. The controller 530 may have a processor, a flash/memory(FLASH/SRAM), and a coding means therein. In addition, the controller530 may use an SPI (Ethernet, EEPROM), TWI (RTC module), or JTAG (SIF)interface.

In a case in which a high impedance balance antenna is matched with alow impedance unbalance receiver, transmitter, or transceiver, a balanceto unbalance (Balun) transformer having high a conversion rate may beused as the transformer 540. For example, in a case in a case in which asignal is a differential signal of 100 ohm, the transformer 540 mayconvert the 100 ohm impedance into 50 ohm impedance according to atransmission/reception signal and may be driven in a filtering matchstate such that only a 2.4 GHz band passes through the antenna.

The filter 550 may be, for example, a low pass filter (LPF) to remove aharmonic component of an output and, at the same time, to filter a highfrequency component of the output. When transmitting a radio frequency(RF) signal, the antenna 560 may couple the signal in the air andreceive an input RF signal. Moreover, the power supply unit 580 mayconvert an input voltage of 5 VDC into a constant voltage of 3.3 VDC andsupply the constant voltage to a ZigBee chip and other parts.

In addition to the above construction, the mobile device 510 may testthe connection status between devices or a memory fusing function ifnecessary. In addition, the mobile device 510 may further include aJoint Test Action Group (JTAG) connector 570 to download a ZigBeesoftware (S/W) program and to perform a debugging function.

Also, the mobile device 510 may further include a memory, a driver, abuffer, an input/output (I/P) port, and an interface (I/F) connector.

The memory may be an Electrically Erasable Programmable Read-Only Memory(EEPROM), which is a kind of non-volatile memory. The memory may have acapacity of, for example, 128 Kbytes. Also, the memory may be used as atemporary data ROM (DataROM) when ZigBee firmware is updated in awireless fashion. Meanwhile, as will hereinafter be described, thememory may store a reference table of values predefined with respect to,for example, color temperature and a dimming level to be referred towhen the controller 530 determines a control level according to theinput at the touch unit 520.

The driver is used in long distance communication with an externaldevice via a differential line in a half duplex mode in UARTcommunication. The buffer may adjust the brightness of the externaldevice (for example, a dimming connector) through width change of, forexample, a 500 Hz pulse in a pulse width modulation (PWM) mode.

The I/O port may be connected to, for example, 12 light emitting unitsthrough RS 485 communication in a half duplex mode to individuallycontrol the light emitting units. The I/O port may receive a voltage of+5 VDC from the external device to drive an internal circuit. The I/Fconnector may receive a voltage of 5 VDC from the external device (forexample, dimming connector) and output a 5 V PWM signal to performdimming, such as down-lighting, through pulse width modulation (PWM)control.

When a high (H) value is input through a selection unit 590, thecontroller 530 may generate a control signal to select and control aroom light. On the other hand, when a low (L) value is input through theselection unit 590, the controller 530 may generate a control signal toselect and control a table light. In a similar manner, the controller530 may determine an input of the selection unit 590 as an input toperform a control function, such as driving of a direct light and anindirect light, and activation of a smart function, and generate acontrol signal to the input.

Meanwhile, the controller 530 may receive a clock signal including aninterrupt signal to determine user input and to generate a controlsignal according thereto.

Also, although not shown, the mobile device 510 may include acommunication module for the aforementioned ZigBee communication. Also,each light emitting unit of the lighting device may include acommunication module for ZigBee communication to receive a controlsignal according to the communication mode of the mobile device. Theaforementioned communication module may be used for future firmwareupgrade.

Meanwhile, as previously described, the lighting apparatus may havelighting effects based on an image, such as an image of a skyline,sunset or sunrise as desired by a user. To this end, the lightingapparatus may further include an image receiving unit to receive animage and an image processing unit to process the received image inaddition to the construction shown in FIG. 5.

FIGS. 6A to 6B are views showing embodiments of a detailed constructionblock diagram of the lighting control device in connection with lightingcontrol.

FIG. 6A shows the construction of the lighting control device in a casein which the lighting control device controls the lighting apparatusthrough an application. The components of FIG. 6A may overlap with thoseof FIG. 5. The components may be modified, removed, or necessarycomponents may be added.

Referring to FIG. 6A, the mobile device may include a touch screen 610,a touch event processing unit 612, a sensor unit 614, a motion patternprocessing unit 616, a controller 618, a communication unit 620, avibration pattern generation unit 622, and a vibrator 624 for motionrecognition of the mobile device and a mobile application to control thelighting apparatus.

The touch event processing unit 612 may determine the attribute and typeof an event input through the touch screen 610 to distinguish acorresponding touch event and transmit data based thereupon to thecontroller 618. The touch screen 610 and the touch event processing unit612 may correspond to the key input receiving unit 510 of FIG. 5.

The sensor unit 614 may sense data input according to a motion of auser, and the motion pattern processing unit 616 may distinguish amotion pattern corresponding to the user motion based on the senseddata. The distinguished motion pattern becomes data to control thelighting apparatus according to the user motion.

The controller 618 may generate data to control the lighting apparatuscorresponding to the user input and motion based on the respectivesignals of the touch event processing unit 612 and the motion patternprocessing unit 616 or a combination of the signals. The generated datamay be transmitted to the lighting apparatus or the vibration patterngeneration unit 622 through the communication unit 620.

The vibration pattern generation unit 622 may generate a correspondingvibration pattern based on the control data generated by the controller618. As previously described, the controller 618 may generate controldata to generate the vibration pattern based on data of the touch eventprocessing unit 612 and the motion pattern processing unit 616 or basedon a signal input from the lighting apparatus through the communicationunit 620.

The vibrator 624 may produce vibration based on the vibration patterndata input from the vibration pattern generation unit 622 to provide afeedback according to the user motion. Meanwhile, in this specification,vibration is illustrated as an example of the feedback. However,embodiments of the present disclosure are not limited thereto. Thefeedback may be provided to the user in various forms, such as soundoutput from a speaker or a related feedback user interface (UI).

FIG. 6B shows an embodiment of the lighting control device to reproducecolor sense data. The lighting control device may include a touch screen650, a touch event processing unit 652, an image receiving unit 654, animage processing unit 656, a controller 658, and a communication unit660.

The touch event processing unit 652 may determine the attribute and typeof an event input through the touch screen 650 to distinguish acorresponding touch event and transmit data based thereupon to thecontroller 658. The image processing unit 656 may sense an image inputthrough the image receiving unit 654 and extract color sense informationfrom the sensed image data. The image processing unit 656 may generatecolor sense data to be applied to the lighting apparatus based on theextracted color sense information or directly transmit the extractedcolor sense information to the controller 658 such that lightingapparatus control color sense data are generated by the controller 658.Meanwhile, the image received by the image processing unit 656 may be animage received from a digital camera or an image directly captured orphotographed by the mobile device.

The controller 658 may generate data to control color sense of thelighting apparatus corresponding to an image input based on therespective signals of the touch event processing unit 652 and the imageprocessing unit 656 or a combination of the signals. The generated dataare transmitted to the lighting apparatus through the communication unit660.

The communication unit 660 may transmit a control signal of thecontroller 658 to the lighting apparatus according to a predeterminedcommunication protocol or transmit a signal of the lighting apparatus tothe controller 658. Also, the communication unit 660 may performnecessary format conversion based on the difference of communicationprotocol between the mobile device and the lighting apparatus.

In the above, a description was made on the basis of the mobile device.However, the lighting apparatus or the lighting system may have an imagereceiving and processing unit to process image data directly input fromthe lighting apparatus, automatically extract related color senseinformation, and express color sense.

Meanwhile, even in a case in which the mobile device is used to controlthe lighting apparatus connected to the mobile device via awired/wireless network as previously described, it is possible to simplyand easily control the lighting apparatus through the motion of themobile device without performing several complicated processes. Also,when controlling the lighting apparatus through the mobile device, afeedback according to a control command may be provided for the user'sconvenience in lighting control.

FIG. 7 is a view showing embodiments for lighting control based onmotion of the mobile terminal. The construction of FIGS. 1 to 6 asdescribed above may be used to distinguish user motion.

User motion as illustrated in FIG. 7 may or may not be a motion relatedto lighting control. This is because a lighting control means asdescribed in this specification may be dedicated for lighting control ora digital device having such a function. In the lighting control meansas shown in FIG. 7, therefore, a process of determining whether usermotion is a motion input for lighting control may be necessary. As anexample of this process, user motion input in a state in which alighting control application is executed may be determined as a motioninput for lighting control.

FIGS. 7(a) to 7(e) show embodiments of various user motions inputthrough, for example, the lighting control device. FIG. 7(a) shows anembodiment of user motion of shaking the lighting control device, FIGS.7(b) and 7(c) show an embodiment of user motion of moving the lightingcontrol device upward and downward, and FIGS. 7(d) and 7(e) show anembodiment of user motion of rolling the lighting control device leftand right.

The above user motions and control functions may be set by a user or setas a default. Also, above user motions and control functions may bechanged. For example, in a case in which the lighting control device isshaken as shown in FIG. 7(a), the user motion may be linked to afunction to turn the lighting apparatus on/off. Also, in a case in whichthe lighting control device is moved upward and downward as shown inFIGS. 7(b) and 7(c), the user motion may be linked to a function toadjust a dimming level up and down. Also, in a case in which thelighting control device is rolled left and right as shown in FIGS. 7(d)and 7(e), the user motion may be linked to a function to adjust a colortemperature level up and down. However, these are illustrated only todescribe a relationship between the motion of the lighting controldevice and the control of the lighting apparatus, and therefore,embodiments of the present disclosure are not limited to the specifiedassignment of a particular motion to a function nor to the listed typesof motion.

In a case in which the lighting control device is shaken as shown inFIG. 7(a), therefore, the user motion may be linked to a function toinitialize the lighting apparatus unlike the above embodiment. Also,when the user shakes the lighting control device, the lighting controldevice may return to a stage or state before the lighting controlcommand is executed or may return to an initial screen of an applicationfor lighting control. Also, the currently set value may be canceled, orthe lighting control device may return to a state before the lightingcontrol mode is executed. Alternatively, in a case in which the lightingcontrol device is shaken, the lighting control or the application forlighting control may be ended. Alternatively, in order to distinguishthe above functions or a function linked to shaking, change may beperformed based on determination as to whether a predetermined item inthe touch screen of the mobile device has been pressed.

Meanwhile, even in a case in which the lighting control device is movedupward and downward as shown in FIGS. 7(b) and 7(c) (or is rolled leftand right), the user motion may be defined, changed, and used so as tobe linked to various functions in addition to the above functions.

For example, after the application is executed in the lighting controldevice, the up and down/left and right motion may function to select acontrol target lighting or predetermined function control list. When theabove motion is performed in a state in which a predetermined functionbutton of the touch screen is pressed, level control of thecorresponding function may be recognized and functioned.

Meanwhile, in a state in which a plurality of function buttons arepressed, the lighting control device may be controlled such that controlrelated to the respective buttons is simultaneously performed. On theother hand, in a state in which a plurality of function buttons arepressed, the up and down motion may be defined as dimming control, andthe left and right motion may be defined as color temperature control.

Also, in the above, the lighting control device may be linked tofunctions related to lighting control even in diagonal motion,rectangular motion, and clockwise or counterclockwise circular motion inaddition to the up and down/left and right motion. As previouslydescribed, on the other hand, the lighting control device may be used tocontrol a plurality of functions and to select control target lighting.

Alternatively, after the lighting control application is executed, andthe user selects control lighting and function, the lighting controldevice may decide a control level on the touch screen and control thecontrol level decided with respect to the control function selectedthrough the up and down/left and right motion to be directly applied tothe corresponding lighting apparatus. That is, the corresponding levelmay be directly controlled through one time of motion. For example, thecorresponding level may be equally controlled through a single instanceof a motion according to the kind, attribute, and type of the motion.

Alternatively, during the above process, a time range or control levelrange may be previously set, and lighting may be gradually controlledaccording to a single instance of a motion or several instances of themotion.

When the control level is decided on the touch screen, the lightingcontrol device may provide the current status of the selected functionof the selected lighting and the status of the decided control level inthe form of a display performance of the lighting control device, a bargraph, or a status bar such that a user can recognize the above statusin advance. Moreover, the screen may be divided such that one half ofthe screen provides the current status and the other half of the screenprovides decided control level, whereby the user can easily recognizethe control degree. Consequently, control of various functions with asingle input may be achieved without deciding the control level severaltimes, thereby enhancing convenience.

In addition, the lighting control device may simultaneously orsequentially control a plurality of bulbs or flat type lightingapparatuses unlike a case in which the lighting control device isassigned to a predetermined lighting apparatus, for example, lightingcontrol in a bedroom, e.g., a single lighting apparatus, such as a bulbor a flat type lighting apparatus.

The lighting control device may previously store a table of motion speedduring up and down/left and right motion and the control level using anacceleration sensor to perform stepwise control and abrupt control basedon the motion speed. Alternatively, the lighting apparatus may becontrolled in a manner similar to the above based on the number of timesof motion repeated similarly to the motion speed. In addition, inconnection with a feedback regarding the lighting control, the lightingapparatus may variously respond to selection of the lighting apparatusor control start/end in addition to the feedback of the lighting controldevice.

The lighting control device may support various modes, such as a sleepmode, a reading mode, a TV watching mode, a movie watching mode, a sportmode, etc. If necessary, the lighting control device may store suchmodes in a state in which the modes are linked to control functions orlevels of the respective functions and automatically control acorresponding mode to be active according to the up and down motion orthe left and right motion when the mode is selected, for example, afterthe mode is pressed or the respective modes to be performed according tothe up and down motion and the left and right motion without touch aftera user interface for mode selection is provided. Alternatively, thelighting control device may link the modes to at least one previouscolor sense data or image such that the linked image or the color sensedata of the image are automatically applied to the corresponding mode orthe corresponding time and output.

The lighting control device may distinguish between continuous usermotion and discontinuous or intermittent user motion to control thelighting apparatus based thereupon. For example, the lighting controldevice may determine a motion performed within 1 to 3 seconds ascontinuous user motion and control the motion to be linked to theprevious motions. On the other hand, the lighting control device maydetermine a motion different from the motion performed within 1 to 3seconds as a motion input different from previous motion inputs andcontrol the lighting apparatus. For example, if no motion input isperformed within a predetermined time, return to the previous state maybe performed, the corresponding application may be ended, or thelighting control mode may be ended.

Hereinafter, a lighting control method will be described with referenceto flowcharts. The lighting control method may include a step ofreceiving a motion of a lighting control device using a wirelesstransmission and receiving unit and a motion recognition sensor, a stepof generating control data according to the received motion of thelighting control device, a step of transmitting the generated controldata to a corresponding lighting apparatus including a wirelesstransmission and receiving unit, and outputting a feedback correspondingto the status of the lighting apparatus according to the control.

The feedback may include at least one selected from among of vibration,sound, UI, and screen blinking or a combination thereof.

Also, the lighting control device may distinguish the type of at leastone motion of the device such as shaking, up and down, right and left,diagonal line, clockwise/counterclockwise circle, or the like, andcontrol at least one of power on/off, color temperature, dimming of thelighting apparatus based on the distinguished type of the motion, orcontrol another appropriate type of function.

In addition, the lighting control device may generate control data of acorresponding function level through a step of setting a critical valueto control the lighting apparatus based on the device motion and a stepof performing a comparison between the input data and the critical valuewhen data regarding the device motion are input.

Also, if continuous motion data are not input within a predeterminedfirst time, the lighting control device may perform at least one of (a)ignoring previously input motion data and waiting for a new motion datainput, (b) generating control data based on the previously input motiondata, or (c) returning to an initial screen if new motion data are notinput before a predetermined second time. In addition, the lightingcontrol method may further include a step of receiving statusinformation regarding current status from the lighting apparatus and astep of deciding the attribute or level of the feedback based on thereceived status information.

The motion recognition sensor may include at least one of anacceleration sensor, a gyro sensor, a pressure sensor, a distancesensor, a tilt or angle sensor, a direction sensor, or anotherappropriate type of sensor. The lighting control device may select atleast one lighting apparatus and/or functions of the selected lightingapparatuses according to a key input of a user, simultaneously controlthe lighting apparatuses or the functions according to the devicemotion. Also, the lighting control device may generate motion data ofthe device only when a lighting control application is executed tocontrol the lighting apparatus. In addition, the lighting control devicemay be at least one of a dedicated remote controller for lightingcontrol, a portable communication device, a portable computing device,or another appropriate type of device.

FIGS. 8 to 10 are flowcharts showing a lighting control processaccording to a motion of the lighting control device.

FIG. 8 is a flowchart showing an embodiment of a motion control methodof the lighting control device. When a user sets an on/off criticalvalue to the lighting control device, in step S802, the motion patternprocessing unit of the lighting control device may sense a motion forpower control, in step S804.

The lighting control device may determine whether the motion sensed atstep S804 exceeds the critical value set at step S802, in step S806. Thelighting control device may determine the current status, such as thecurrent power on/off status, of a corresponding lighting apparatus afterstep S806 or during step S806, in step S808.

Upon determining at step S806 that the sensed motion exceeds the setcritical value and upon determining at step S808 that the correspondinglighting apparatus is on, the lighting control device may turn off thecorresponding lighting apparatus according to the motion, in step S810.On the other hand, upon determining at step S808 that the correspondinglighting apparatus is off, the lighting control device may turn on thecorresponding lighting apparatus according to the motion, in step S812.

When the corresponding lighting apparatus is turned on at step S812, thelighting control device may determine whether a motion key of the keyinput unit has been pressed, in step S814. Upon determining that themotion key of the key input unit has been pressed, in step S816, themotion pattern processing unit of the lighting control device may sensethe motion, in step S818, generate a control signal to control a dimminglevel and a color temperature level according to the attribute of thesensed motion, and transmit the generated control signal to thecorresponding lighting apparatus through the RF transmission unit,thereby controlling the corresponding lighting apparatus through themotion of the lighting control device, in step S820.

FIG. 9 is a flowchart showing an example of a method of controlling thelighting apparatus based on a motion in detail. In this example, athree-axis acceleration sensor is used as the sensor, and functionsrelated to dimming and/or color temperature are performed.

First, the lighting control device may automatically set a sensorcritical value according to user input or as default, in step S902, andmay detect an X axis value and a Y axis value of the accelerationsensor, in step S904 and S906, respectively.

The lighting control device compares the positive X axis value and thepositive Y axis value of the acceleration sensor with each other and maycontrol different functions to be performed when the X axis value of theacceleration sensor is higher or when the Y axis value of theacceleration sensor is higher, in step S908.

For example, in a case in which the X axis value of the accelerationsensor is higher at step S908, the X axis value of the accelerationsensor may be compared with the sensor critical value, in step S910. Ifthe X axis value of the acceleration sensor is lower than the negativesensor critical value, the color temperature level may be decreased, instep S912, and, if the X axis value of the acceleration sensor is higherthan the positive sensor critical value, the color temperature level maybe increased, in step S914. In this case, if the X axis value of theacceleration sensor is between the negative sensor critical value andthe positive sensor critical value, which means that the X axis value ofthe acceleration sensor is within a range of critical value, no functionlevel control may be performed. Meanwhile, in the above control method,dimming may be controlled in addition to the color temperature.

Also, in a case in which the Y axis value of the acceleration sensor isdetermined to be higher at step S908, the Y axis value of theacceleration sensor is compared with the sensor critical value, in stepS916. If the Y axis value of the acceleration sensor is lower than thenegative sensor critical value, the brightness (dimming) level may bedecreased, in step S918, and, if the X axis value of the accelerationsensor is higher than the positive sensor critical value, the brightnesslevel may be increased, in step S920. In this case, if the Y axis valueof the acceleration sensor is between the negative sensor critical valueand the positive sensor critical value, which means that the Y axisvalue of the acceleration sensor is within a range of critical value, nofunction level control may be performed. Meanwhile, in the above controlmethod, color temperature may be controlled in addition to thebrightness.

FIG. 10 is a flowchart showing an example of a method of controlling alighting control application. The lighting control device may determinewhether the motion button of the touch screen has been manipulatedthrough the touch input processing unit and transmit the determinationresult to the controller, in step S1002.

The controller may determine whether the motion button has been pressed,in step S1004. Upon the controller determining at step S1004 that themotion button has been pressed, the motion pattern processing unit maysense a motion, e.g., an up and down, and left and right tilt of thelighting control device, in step S1006. The controller may generate acontrol signal to control a dimming or color temperature level based onthe sensed motion data, and transmit the generated control signal to acorresponding lighting apparatus through the RF transmission unit, instep S1008.

Subsequently, the controller may periodically or non-periodicallyreceive status information regarding the current temperature color orthe current dimming from the corresponding lighting apparatus throughthe RF receiving unit and may store the received status information, instep S1010. The controller may determine the current level of thelighting apparatus based on the received status information of thelighting apparatus, in step S1012. For example, if the current level ofthe lighting apparatus is the minimum, the controller may control ashort vibration feedback to be generated, in step S1014, and, if thecurrent level of the lighting apparatus is the maximum, the controllermay control a long vibration feedback to be generated, in step S1016.

Meanwhile, on the assumption that the function level has four steps, thecontroller may control vibration to be generated shortly three timeswhen the step of the current level is a third step such that easierrecognition can be achieved according to the respective steps of thefunction level.

In addition, the controller may generate sound through a speaker orprovide a related graphical user interface (GUI) either together withthe vibration feedback or in lieu of the vibration feedback such thatthe user can easily recognize the function.

As described above, it is possible to control a lighting apparatusconnected to a lighting control device via a wired/wireless networkusing the lighting control device. Meanwhile, it is possible to controlthe lighting apparatus through the motion of the lighting control devicewithout performing several complicated processes. In a case in which thelighting apparatus is controlled through the lighting control device, afeedback according to a control command may be provided for the user'sconvenience in controlling the lighting. Also, it is possible to improveuser's convenience, product satisfaction, and marketability through thelighting system including the lighting apparatus and the lightingcontrol device to control the lighting apparatus.

FIG. 11 is a view showing the lighting control device or the touchscreen included in the lighting control device. The lighting controldevice 1100 may include a front part and a side part. The front part ofthe lighting control device 1100 may be divided into three regions. Atthe side part of the lighting control device 1110 may be provided abutton designated as a hold button 1101 to control a user input toperform overall functions and an operation based thereupon in a state inwhich the lighting control device is on. In this example, the holdbutton 1101 is provided at a portion of the side part, for example aright side part, of the lighting control device 1100. However,embodiments of the present disclosure are not limited thereto. Forexample, the hold button may be provided at a left side part, an upperside part, or a lower side part of the lighting control device. Also, apower button or a predetermined function button may be further providedat the side part of the lighting control device in addition to the holdbutton 1101.

Hereinafter, the front part of the lighting control device 1100 will bedescribed in detail. In the following description, the front part of thelighting control device 1100 may be divided into a first region 1110, asecond region 1120, and a third region 1130, as previously described.

First, the first region 1110 may be located at the upper part of thelighting control device 1100. The first region 1110 may include a shadepower button 1111 to turn on/off the lighting control device 1100, ahold display icon 1112 to display whether the lighting control device isheld according to selection of the hold button 1101 provided at the sidepart of the lighting control device, and first function icons 1113,1114, 1115.

The power button 1111 may be realized as, for example, a tactile switchtogether with the hold button 1101 provided at the side part of thelighting control device 1100. Also, a backlight light emitting diode(LED) provided in the power button 1111 or the hold display icon 1112may be turned on/off such that a user can immediately recognize whetherthe lighting control device 1100 is on/off and whether a hold functionis activated. Also, in a case in which the hold button 1101 is notprovided at the side part of the lighting control device, the holdbutton may be realized as a tactile switch in the first region 1110together with the power button 1111. In addition, a side knob may beapplied to the hold button provided at the side part of the lightingcontrol device, and the position of the hold button may be changed.

The first function icons 1113, 1114, 1115 may include at least one of adirect light selection function icon 1113, and an indirect lightselection function icon 1114 based on the type of a light emitting unit,and a smart function icon 1115 to control a smart mode operation withrespect to a direct light and/or an indirect light, or anotherappropriate function icon. In other words, when a user selects at leastone of a direct light selection function, an indirect light selectionfunction, or a smart function through the lighting control device, theselected function may be displayed to indicate its activated state.Although the first function icons 1113, 1114, 1115 display whether thecorresponding functions are activated in the form of icons in thisexample, the first function icons may be realized in the form of touchkeys or tactile switches like the above power button 1111 and the holdbutton 1101 such that the corresponding functions can be directlyselected. Also, each of the first function icons may adopt a backlightLED. A yellow-green LED may be used as the backlight LED. Consequently,the first function icons may display whether corresponding functions areactivated as previously described.

The first function icons 1113, 1114, 1115 are provided for a kind ofgroup control. In a case in which identical control is impossibleaccording to characteristics of the light emitting unit, the firstfunction icons 1113, 1114, 1115 are provided for the user's convenience.Meanwhile, the smart function may be realized or controlled although thedirect light or the indirect light is not selected.

The first function icons 1113, 1114, 1115 are provided to select thelight emitting unit or perform the smart function. On the other hand,second function icons 1131, 1132, 1133, 1134 of the third region 1130are provided to perform various mode control functions. The mode controlfunctions may include, for example, a meal mode, a wine mode, a teatimemode, a reading mode, or the like. Icons for the corresponding modes maybe provided such that users can easily recognize the modes. Althoughspecial icons are not provided as shown in FIG. 11, specially requestedmodes may be stored and used according to user selection. In this case,various modes may be provided in addition to the above modes. First ton-th (n being a positive integer) modes may be stored in the memoryaccording to user selection and may display whether correspondingfunctions are activated. Meanwhile, a light emitting mode may beoperated in a contextual mode including a plurality of mode icons presetin consideration of at least one of time, weather, user intention, thesurroundings, or the like, with respect to the icon selected in thethird region 1130.

The second region 1120 may include a touch screen 1121. For example, agradation of n points×m points as shown in FIGS. 11 and 12 may beapplied to the touch screen 1121. Meanwhile, the touch screen of thesecond region may recognize user input through, for example, thegradation to minutely and more accurately control color temperature anddimming. For example, 256-step control is possible. Control of the colortemperature and the dimming will be described in detail with referenceto FIG. 18, which will hereinafter be described.

Meanwhile, the touch screen 1121 of the second region 1120 may beinterlocked with the first region 1110 and the third region 1130 inaddition to the input for control. Alternatively, the touch screen 1121of the second region 1120 may display various data or output the datatogether with audio. For example, in a case in which the lightingcontrol device is on, it is possible to display the on-state of thelighting control, remaining battery power of the lighting controldevice, a memory status (total capacity, available capacity, etc.),whether the hold button is activated, whether a predetermined functionis activated, whether the light emitting unit selected together with mapinformation is displayed when the first function icons 1113, 1114, 1115are selected through the touch screen 1121 of the second region 1120, orthe like. In other words, the touch screen 1121 of the second region mayperform a window function to display various functions of the lightingcontrol device and provided related data, together with means to inputpoint information for lighting control.

In the above, examples of the first function icons 1113, 1114, 1115 andthe second function icons 1131, 1132, 1133, 1134 were illustrated.However, the first function icons and the second function icons are notlimited to the illustrated examples. The first function icons and thesecond function icons may be realized in a specific region of thelighting control device at various positions and in various forms forthe user's convenience. For example, the positions of the first functionicons and the positions of the second function icons may beinterchanged. The second function icons may be located under the firstfunction icons, or the first function icons may be located under orabove the second function icons. The first function icons and/or thesecond function icons may be aligned vertically rather than horizontallyon the display.

In addition, the region in which the first function icons and/or thesecond function icons are disposed may be provided in the form of atouch screen instead of fixed icons, and corresponding icons may beprovided according to user selection. In this case, the first functionicons and/or the second function icons may be included in the touchscreen 1121 of the second region such that the first function iconsand/or the second function icons can be displayed in predeterminedregions only according to user request. Meanwhile, the entirety of thelighting control device 1100 may be configured in the form of a touchscreen. In this case, the above function icons may be displayed inpredetermined regions of the touch screen all the time or only accordingto function request.

The lighting control device may enter into a sleep mode to reduce powerconsumption a predetermined amount of time after the final key input isperformed. The predetermined time may be, for example, 10 seconds. Inthe sleep mode, some buttons, such as the power button, or some iconsmay be realized such that LED brightness of the buttons or the icons canbe adjusted or pictographs of the buttons or the icons can be displayedat predetermined power levels, and therefore, at least the position ofthe lighting control device can be recognized. When a user presses aspecific button while in the sleep mode such as the power button or thehold button, or a specific region such as the touch region, the sleepmode may be released, and the lighting control device enters into awake-up mode. The wake-up mode is opposite to the sleep mode. In thewake-up mode, various functions may be performed according to selectionof corresponding buttons or icons. Even when any portion of the frontpart or the side part of the lighting control device is touched insteadof a specific button or icon to release the sleep mode of the lightingcontrol device, the sleep mode may be released, and the lighting controldevice may enter into a wake-up mode.

As previously described, the touch screen of FIG. 11 may serve as meansto control color temperature and dimming of the light emitting unit.

FIG. 12 is a view showing embodiments of a relationship between thetouch screen and lighting control according to touch and drag, and FIG.13 is a view showing embodiments of control scenarios of FIG. 12. Simplyfor ease of description FIG. 12 illustrates a situation in which thetouch screen of FIG. 11 is used as a rectangular coordinate system toexecute a lighting control method. The rectangular coordinate systemcorresponds to, for example, the gradation of n points×m points aspreviously described.

In FIG. 12, the vertical axis Y indicates a color temperature level, andthe horizontal axis X indicates a dimming level for the sake ofconvenience. However, embodiments of the present disclosure are notlimited thereto. That is to say, the vertical axis Y may indicate adimming level, and the horizontal axis X may indicate a colortemperature level. Also, numbers of the vertical axis Y and thehorizontal axis X may indicate previously assigned control levels forthe sake of convenience. The control levels may be previously stored inthe memory of the lighting control device in the form of a table.Consequently, a control degree may be preset for each level.

Referring to FIG. 12, the color temperature level and the diming levelmay be individually or simultaneously controlled. Of course, otherfunctions may be controlled in the same manner according to userselection in addition to the color temperature and the dimming.

For example, when a user wishes to control the color temperature or thedimming through the lighting control device, the user may activate oneof the functions and touch a desired point.

In this case, a grid may be formed as shown in FIG. 11 for the user'sconvenience. For example, three points, such as a first point 1211, asecond point 1213, and a third point 1215, are shown in FIG. 12. Thefirst point 1211 may control the color temperature level or the diminglevel to a second level according to a requested function. Of course, ina case in which two functions are simultaneously requested, both thecolor temperature level and the diming level may be controlled to thesecond level.

In this case, the controller 530 of the lighting control device receivesinformation regarding the point touched by the user from the touch unit520, compares the received point information with the previouslyrequested function to decide a control level corresponding to the pointinformation, generates a control signal to control a function level of acorresponding light emitting unit to the request level, and transmitsthe generated control signal. The second point 1213 may induce pointinformation regarding dimming having a second level and colortemperature having a third level, and the third point 1215 may inducepoint information regarding dimming having a third level and colortemperature having a third level. The induced point information istransmitted to the controller 530 via the touch unit 520 such that theinduced point information can be used to generate a control level.

In this case, the touch screen 1121 of the lighting control device maybe divided into left and right regions and upper and lower regions, andcolors may be displayed in the respective regions such that the user canmore easily perform control according to the degree of the lightingcontrol level. For example, a blue color may be provided at the leftregion of the touch screen, and a red color may be provided at the rightregion of the touch screen. The concentration of the colors may bechanged in the vertical direction or in the horizontal direction suchthat the level is increased as the colors become dark and the level isdecreased as the colors become light for the user's convenience inselection. Also, in a case in which only one color is used, theconcentration of the color may be increased from the left lower side tothe right upper side of the touch screen as shown in FIG. 12 for theuser's convenience in selection. However, embodiments of the presentdisclosure are not limited thereto. Various methods may be adopted forthe user's convenience in recognition and/or selection.

The above description is related to, for example, a case in which a usertouches at least one point. Meanwhile, the user may not touch apredetermined point of the touch screen but may drag a predeterminedpoint after the point is touched.

The drag input may include a first drag 1220 in the vertical direction,a second drag 1230 in the horizontal direction, and a third drag 1230 inthe diagonal direction. In case of the first drag 1220 and the seconddrag 1230, it may not be necessary to select a pre-control function. Forexample, the first drag 1220 is performed only in the verticaldirection. As a result, a control level of the color temperature may bedetermined, but a control level of the dimming may not affected. Also,the second drag 1230 is performed only in the horizontal direction. As aresult, a control level of the dimming may be determined, but a controllevel of the color temperature may not be affected.

In case of the first drag 1220, the touch unit 520 may collectinformation regarding a plurality of points, including a first point toan n-th point. At this time, the touch unit 520 may extract first pointinformation regarding the first touched portion and second pointinformation regarding the last touched portion and transmit theextracted information to the controller. The controller 530 maycalculate the difference in levels or values between the second pointinformation and the first point information input from the touch unit520 to decide a control level, generate a control signal based on thedecided control level, and transmit the generated control signal to acorresponding light emitting unit. The control signal may be generatedbased on, for example, information regarding the current level of thecorresponding light emitting unit. In other words, if the decidedcontrol level is a second level, the controller 530 may generate acontrol signal to change the current level of the corresponding lightemitting unit to the second level, and transmit the generated controlsignal to the corresponding light emitting unit. Alternatively, thecontroller 530 may receive information regarding the current level ofthe corresponding light emitting unit, calculate a value different fromthe current level to be two levels, generate a control signal containinga level based on the calculated value, and transmit the generatedcontrol signal to the corresponding light emitting unit.

The second drag 1230 is identical to the first drag 1220 except that thesecond drag 1230 is not performed in the vertical direction but isperformed in the horizontal direction.

Also, the controller 530 may increase and decrease the first point andthe second point based on a first touch point and a second touch point.If the value is positive, the level may be increased, and, if the valueis negative, the level may be decreased. The positive value indicates acase in which the level of the first touch point is lower than that ofthe second touch point, and the negative value indicates a case in whichthe level of the first touch point is higher than that of the secondtouch point.

In case of the first drag 1220 and the second drag 1230, only the colortemperature level and the dimming level, respectively, may beindividually controlled. In case of the third drag 1240, on the otherhand, the drag is performed in the diagonal direction. In this case, itis possible to simultaneously control the color temperature and thedimming using information regarding a plurality of touch points of thetouch unit 520 in the same manner as in the first drag 1220 and thesecond drag 1230.

For example, the touch unit 520 may extract first point informationregarding the first touched portion and second point informationregarding the last touched portion and transmit the extractedinformation to the controller in the same manner as in the first drag1220 and the second drag 1230. Alternatively, the touch unit 520 mayalso provide a third point information regarding an intersection betweenthe horizontal axis and the vertical axis of a rectangular coordinatesystem together with the first point information regarding the firsttouched portion and the second point information regarding the lasttouched portion. Referring to FIG. 12, on the assumption that thedimming corresponds to an X coordinate on the X axis and the colortemperature corresponds to a Y coordinate on the Y axis of therectangular coordinate system, coordinate (2, 1) is first pointinformation, (5, 3) is second point information, and (5, 1) is thirdpoint information.

When the touch unit 520 transmits the above coordinates of therectangular coordinate system, i.e., a plurality of pieces of pointinformation, to the controller 530, the controller 530 may decidecontrol levels of the color temperature and the dimming using the inputpoint information to generate a control signal and transmit thegenerated control signal to a corresponding light emitting unit. In thiscase, the control signal may be individually generated with respect tothe color temperature and the dimming. Alternatively, the control signalmay be commonly generated with respect to the color temperature and thedimming. For example, in case of the third drag shown in FIG. 12, thecontroller 530 may generate a control signal to control the dimming tohave a third level and the color temperature to have a second levelbased on the third point information.

Also, the controller 530 may generate a control signal to control thedimming and the color temperature to have the same level according topoint information regarding the dimming and the color temperature. Forexample, in case of the third drag 1240, the controller 530 may controlthe dimming and the color temperature to have the same level (forexample, both the dimming and the color temperature have k level, wherek is a positive integer) according to a drag degree based on informationregarding a plurality of points, and may previously define values basedon the point information in the form of a table.

FIGS. 13A to 13C show examples of a dimming control operation, a colortemperature control operation, and a dimming and color temperaturecontrol operation. Here, a touch and drag input in the verticaldirection may be performed to control dimming, and a touch and draginput in the horizontal direction may be performed to control colortemperature, unlike FIG. 12. Functions of the lighting control devicemay be predefined. Alternatively, functions of the lighting controldevice may be changed or modified according to user selection.

In this embodiment, color temperature and dimming are controlled.However, embodiments of the present disclosure are not limited thereto.For example, the lighting control device may be set to define or controlvarious functions according to user selection.

In the above description, in a case in which the controller 530generates a control signal according to the point information of thetouch unit 520, the control signal is transmitted to control acorresponding light emitting unit after all touch operations arecompleted. In this case, however, it may be necessary to perform severaltouch and control operations in order to accurately perform control at alevel desired by a user. In order to solve this problem, in case of thetouch and drag, information regarding the touch point may be directlytransmitted to the controller 530 every touch from the first touchedportion although the touch is not completed, and the controller 530 maygenerate a control signal and transmit the corresponding light emittingunit. That is, the lighting may implement the changes instantaneously toprovide feedback to the user. As a result, the user may directlydetermine to what extent the current touch status of the lightingcontrol device is controlled using visual feedback from the lightingsuch that the control process can be completed through a single touchand drag input. In this case, the corresponding function of the lightemitting unit may be controlled, and therefore, the user may determinethe control degree based on the touch with the naked eye such that thecontrol process can be completed through a single touch and drag input.

Moreover, in addition to dimming and color temperature, the displayedgrid of FIG. 13 may be used to select a color using, for example, acolor palette displayed on the screen. Here, various touch inputs may beused to change the color of the light source based on the color selectedon the color palette. Furthermore, it should be appreciated that thedimming and color temperature as well as color or another appropriatecontrol function may be controlled using other types of input interfacessuch as scroll bars, or the like.

FIGS. 14 to 16 are flowcharts showing a lighting control processaccording to touch in the lighting control device. Referring to FIG. 14,which shows an example of a lighting control method using the lightingcontrol device, the lighting control device is connected to at least onelight emitting unit, in step S1410. Connection between two devices mayindicate a process to perform transmission and reception of data betweenthe devices through, for example, the aforementioned specificcommunication protocols. This process may be referred to as aninitialization process, which is performed before a control process.

When the lighting control device is connected to the light emitting unitat step S1410, the lighting control device may acquire a control degree,e.g., point information, desired by a user through the touch screen, instep S1420. This process may be performed by the touch unit 520. In acase in which a plurality of pieces of point information exists aspreviously described, the touch unit 520 may individually extract firstpoint information and second point information or first pointinformation to third point information and transmit the extracted pointinformation to the controller 530. Alternatively, whenever pointinformation is generated, the touch unit 520 may immediately transmitthe generated point information to the controller 530.

The controller 530 decides a control level based on the acquired pointinformation, in step S1430. This process may be performed in the samemanner as in FIG. 12. The controller 530 may generate a control signalaccording to the control level decided at step S1430 and transmit thecontrol signal to the light emitting unit such that the light emittingunit can be controlled according to the control signal, in step S1440.

Next, another example of a lighting control method using the lightingcontrol device will be described with reference to FIG. 15. A detaileddescription will be omitted of steps of the lighting control methodaccording to this example identical to those of the lighting controlmethod according to the previous example. In other words, steps S1510and S1520 of FIG. 15 are identical to steps S1410 and S1420 of FIG. 14,and therefore, a detailed description thereof will be omitted.

The controller 530 may acquire point information from the touch unit 520and information regarding the current level (first level) of acorresponding light emitting unit simultaneously when the pointinformation is acquired, before the point information is acquired, orafter the point information is acquired, in step S1530, and decide alevel (second level) mapped with the acquired first level and the pointinformation acquired by the touch unit 520, in step S1540. Thecontroller may then calculate the difference between the first level andthe second level, in step S1550.

The controller 530 may generate a control signal to control thecorresponding light emitting unit to a specific level according to thedifference between the first level and the second level and transmit thegenerated control signal to the corresponding light emitting unit, instep S1560.

The second level may be decided based on, for example, first pointinformation and second point information or first point info nation tothird point information. Alternatively, the mapping level of the secondlevel may be decided based upon a predetermined mapping table.

As previously described, the control signal may be transmitted to thelight emitting unit in a state in which the level difference iscontained in the control signal such that the level is increased ordecreased by a corresponding level value. Alternatively, the controllermay previously calculate the level difference, decide a valuecorresponding to the level difference, and transmit a control signalincluding the decided level value to the light emitting unit such thatthe level of the light emitting unit can be changed to the correspondinglevel. That is, in the former case, the different level is transmittedto control the light emitting unit based on the different level. In thelatter case, a level to be changed is specified based on the differentlevel calculated by the controller and the current level of the lightemitting unit, and the light emitting unit is controlled based on thespecified level.

FIG. 16 is similar to FIG. 15, and therefore, only construction of FIG.16 different from that of FIG. 15 will be described. In FIG. 16,direction information may be added to the construction of FIG. 15.

Upon receiving point information at steps S1610 and S1620, thecontroller may extract first point information and second pointinformation or first point information to third point information from aplurality of pieces of point information, in step S1630. In addition,the controller may extract direction information, in step S1640, decidesa control function and a control level based on the extracted pointinformation and the extracted direction information, in step S1650,generate a control signal according to the decided control level, andtransmit the generated control signal to a light emitting unit such thatthe light emitting unit can be controlled according to the controlsignal.

FIG. 17 is a view showing embodiments of an image processing method,such as color sense data generation, for color sense reproduction in thelighting apparatus. In describing FIG. 17, FIG. 6(b) will be referred tofor the sake of convenience.

In order to process image data, the construction blocks of FIGS. 1 to 6as described above may be used. Moreover, the image processing methodmay be provided in the form of an application such that the lightingcontrol device can be set as a lighting control means according to thecharacteristics of the lighting control device. As the application isexecuted, the lighting control device may perform lighting control,e.g., image data processing.

For example, FIG. 17(a) shows image capture as an example of an imageacquisition process through the lighting control device, and FIGS. 17(b)to 17(d) show image processing methods. Once the image is displayed, aparticular region of the image may be selected for use in controllingthe lighting. The selected region may be adjusted by inputs on thedisplay screen, and may be a selection of regions of various sizes or aprescribed point in the image. Moreover, the image need not be captured(e.g., a picture photographed and stored), but may be focused using thecamera to be displayed on the screen for use in selecting a color orcolor pattern. The image processing methods may include a mosaic patternprocessing method, a gradation pattern processing method, and a colorpercentage pattern processing method. Specifically, FIG. 17(b) shows themosaic pattern processing method, FIG. 17(c) shows the gradation patternprocessing method, and FIG. 17(d) shows the color percentage patternprocessing method.

As previously described, 17(b) to 17(d) show criteria on how color sensedata to be applied to the lighting apparatus are processed andconfigured. Referring FIG. 17(b), the lighting control device may cropor resize a selected or photographed image and set a mosaic intervalpixel size. At this time, such setting may be performed with referenceto the width of the image, the number of LED elements in the horizontaldirection, the height of the image, and the number of the LED elementsin the vertical direction. The lighting control device may extract RGBvalues in unit of the pixel size set as described above. The lightingcontrol device may generate pixels having the extracted RGB values. Theabove process may be performed with respect to each of the pixelsassigned to the cropped or resized image such that the light emittingunit of the flat type lighting corresponding to the respective pixels orthe flat type lighting corresponding to the respective pixels outputsvarious color senses.

Alternatively, the lighting control device may reflect the input imagedata to the lighting in the form of a mosaic. To this end, the imageprocessing unit 656 may divide the input image data in the form of amosaic, e.g., into mosaic units having predetermined ranges, and extractcolor sense data (for example, color temperature data) corresponding tothe respective mosaic units.

The image processing unit 656 may compare the extracted color sense datawith color sense data that can be realized in the lighting apparatus todecide and configure the optimum lighting control color sense data. Indeciding and configuring the lighting control color sense data, thecolor sense data of only the corresponding mosaic may be referred to, orthe color sense data of a mosaic adjacent to the corresponding mosaicwithin a predetermined range may be referred to. Also, in deciding thelighting control color sense data, in a case in which there are no colorsense data that can be realized in the lighting apparatus, color sensedata of the corresponding mosaic may be decided by referring to colorsense data closer to the border color sense data or color sense data ofthe aforementioned neighboring mosaic. On the other hand, apredetermined number of, for example 6, mosaics may be decided as areference unit of lighting control color sense data instead of onemosaic such that color sense data can be decided and configured. In thiscase, a gradation method or a color percentage method may be used withrespect to a plurality of mosaics.

The controller 658 may generate link data linked to a plurality of lightemitting diodes belonging to a lighting apparatus, such as a flat typelighting apparatus, based on the lighting control color sense datagenerated by the image processing unit 656. The link data may becombined to generate a control signal with respect to the flat typelighting apparatus. On the other hand, in a case in which a plurality offlat type lighting apparatuses is provided, the mosaic may beappropriately assigned and linked to the respective flat type lightingapparatuses, and color sense data and link data are generated withrespect to the mosaics corresponding to the respective flat typelighting apparatuses. As a result, the aforementioned lighting controlsignal may be transmitted.

Consequently, it is possible to output various color sensescorresponding to an image through one flat type lighting apparatus or tooutput the same color senses through a plurality of flat type lightingapparatuses.

Referring to FIG. 17(c), a color range may be selected from the inputimage data, and the selected color may be reflected in lighting as agradation. The image processing unit 640 may extract data on a colorrange from an image, and automatically or manually selects a desired orappropriate color range from the extracted color range.

The image processing unit 656 may decide a color corresponding to theselected color range and decide a gradation degree corresponding to thedecided color to generate gradation data. The controller 658 maytransmit the gradation data, received from the image processing unit656, to a flat type lighting apparatus such that the flat type lightingapparatus outputs a gradation effect corresponding to the receivedgradation data.

On the other hand, in a case in which the controller 658 simultaneouslycontrols a plurality of flat type lighting apparatuses, the controller658 may control the respective flat type lighting apparatuses to havethe same gradation effect or different gradation effects. For example,the controller 658 does not select one color from the color range outputfrom the image but selects colors corresponding to the flat typelighting apparatuses to be controlled and arranges the selected colorswith respect to the respective flat type lighting apparatuses such thatthe flat type lighting apparatuses can appropriately output gradationeffects.

Referring to FIG. 17(d), one of RGB colors which is the most distributedin the input image is determined from input image data and is reflectedin the lighting apparatus. The image processing unit 656 may extractdata regarding the RGB colors from the image and calculates percentagesof the RGB colors from the extracted data. The image processing unit 656may decide one color which is the most distributed from the RGB colorsbased on the calculated percentages of the RGB colors to generate thecolor sense data.

The controller 658 may transmit a control signal containing the colorsense data decided and generated by the image processing unit 656 to thelighting apparatus such that the lighting apparatus can express colorsense corresponding to the data. Meanwhile, in a case in which aplurality of flat type lighting apparatuses is controlled by thecontroller 658, the controller 658 may apply the most distributed colorto all of the flat type lighting apparatuses in a bundle. Alternatively,the controller 658 may control the respective flat type lightingapparatuses to have colors appropriately corresponding to R, G, and B.

At this time, R, G, and B may be controlled at the same degree ofluminous intensity based on the distribution ratio thereof. For example,it is assumed that a certain image has a distribution ratio of 50% R,30% G, and 20% B. In a case in which a R color is assigned to firstlighting, a G color is assigned to second lighting, and a B color isassigned to third lighting, color sense different from that of the aboveimage may be felt when the three lightings have the same luminousintensity. Consequently, the controller 658 may control the luminousintensities of the G lighting and the B lighting to be lowered accordingto the distribution ratio based on the luminous intensity of the Rcolor, which is the most distributed. In this case, better effects maybe provided. Alternatively, the R, G, and B data may be appropriatelyarranged in time order or based on a PWM signal, or a combination of theR, G, and B data corresponding to the color sense data may betransmitted in time order while being synchronized by the PWM signal.

Meanwhile, in a case in which the controller 658 simultaneously controlsfour or more flat type lightings together with or independently from theabove description, the controller 658 may assign appropriate colors tothe respective lightings based on the color sense distribution of thedata such that appropriate effects can be provided.

Also, in a case in which the controller 658 assigns one color (forexample, the most distributed color) to the respective flat typelightings, the controller 658 may control even the same color to havedifferent luminous intensities according to the arrangement such thatsimilar effects can be provided.

Also, the controller 658 may control one flat type lighting or aplurality of flat type lightings using a single color pattern. Inaddition, the controller 658 may apply different color patterns to therespective flat type lightings or may apply a combination of the threecolor patterns to the respective flat type lightings. What color patternis to be applied may be automatically decided. Alternatively, what colorpattern is to be applied may be preset or decided according to userinput.

Meanwhile, all contents related to generation of the color patterns andthe lighting control color sense data may be performed by the controllerof the lighting apparatus, not the mobile device. Alternatively, datarelated to color sense may be extracted by the mobile device, anddecision of the color pattern and generation of pattern values, i.e.lighting control color sense data, may be performed by the controller ofthe lighting apparatus. Alternatively, both the mobile device and thelighting apparatus may generate color sense data, the color sense datagenerated by the mobile device and the color sense data generated by thelighting apparatus may be compared, and an average value may be appliedaccording to the comparison result.

Meanwhile, each color pattern unit may correspond to one dot or aplurality of dots of an image. Also, in configuring color sense dataregarding an image, the image and the flat type lighting may becompared, the image may be appropriately resized and converted, and acolor pattern unit may be configured differently from the previous colorpattern unit based on the converted image.

In order for the respective light emitting units of each flat typelighting or the respective flat type lightings to have different colorsenses, for example, the amount of current introduced into therespective light emitting units of each flat type lighting or therespective flat type lightings may be adjusted based on the color sensedata. Meanwhile, the lighting apparatus or the mobile devices maypreviously construct a table regarding the amount of current and thecolor sense data such that the lighting can be more rapidly and easilycontrolled.

Also, as previously described, the mobile device or the lightingapparatus may previously configure and store an image and lightingcontrol color sense data on the image. Consequently, it is possible topreviously control the lighting apparatus to have appropriate luminousintensity at appropriate time through a schedule function.

In addition, even in a case in which an image is not captured by a userbut is merely focused using a camera, for example, the above process maybe performed, a mode based on the previously stored lighting controlcolor sense data may be provided according to the user's request, thelighting may be automatically controlled according to the mode, or thelighting control color sense data may be recommended according to theuser's request. Particularly in the latter case, the mobile device orthe lighting apparatus, which is capable of recognizing sensitivity, maydetermine surroundings, time, or sound to automatically apply orrecommend appropriate lighting control color sense data.

FIG. 18 is a view showing an embodiment in which color sense isreproduced according to a lighting control method. Specifically, FIG.18(a) shows a state before lighting control is performed, and FIG. 18(b)shows a state after lighting control is performed.

Hereinafter, a lighting control method will be described with referenceto a flowchart.

One example of the lighting control method may include a step ofreceiving an image, a step of extracting color sense pattern data of theimage in a predetermined unit to generate lighting control color sensedata, a step of deciding a light source of a lighting emitting unitcorresponding to the predetermined unit of the received data based onthe generated lighting control color sense data, and a step ofcontrolling a corresponding lighting emitting unit using the lightsource decided based on the lighting control color sense data. Thelighting control method may further include a step of reconfiguring thereceived image such that the received image corresponds to a lightingapparatus.

Meanwhile, the lighting control color sense data may be generated usingat least one of a mosaic pattern processing method, a gradation patternprocessing method, a color percentage pattern processing method, oranother appropriate method. Also, the lighting control method mayfurther include a step of assigning a mosaic interval pixel size to thereconfigured image, a step of extracting RGB values into the assignedpixel size unit, and a step of generating pixels having the extractedRGB values. Also, the lighting control method may further include a stepof generating a mosaic image, a step of selecting at least one colorwithin a color range, and a step of generating gradation based on theselected at least one color.

Alternatively, the lighting control method may further include a step ofgenerating a mosaic image, a step of calculating percentages of a redcolor (R), a green color (G), and a blue color (B), and a step ofdistinguishing a color having the highest percentage from the colorshaving the calculated percentages and deducing an average of the colors.The predetermined unit may be a dot unit, and the color sense patterndata and/or the lighting control color sense data may include colortemperature and/or luminous intensity. Moreover, the image may bereceived from a lighting control device and/or an external device. Inaddition, the lighting unit may include flat type lighting.

FIGS. 19 to 22 are flowcharts showing embodiments of an image processingmethod for color sense reproduction. Hereinafter, image processingmethods for color sense control will be described as individualembodiments. Alternatively, the individual embodiments may be combinedto process an image for color sense control.

FIG. 19 is a flowchart showing an example of a color sense controlmethod of the lighting control device. When a user selects orphotographs an image, in step S1902, the lighting control devicedetermines whether the selected or photographed image is to be used forlighting control, in step S1904. The image may be selected from a photogallery in the lighting control device. Meanwhile, photographing alsoincludes capturing or focusing a motion image or a still image inaddition to photographing the motion image or the still image. In caseof focusing, a focus factor, such as a rectangular box, according touser selection may be used.

Upon determining at step S1904 that the corresponding image is to beused for lighting control, the lighting control device may determine andselect what lighting control pattern, e.g., what color sense pattern, isto be applied to the image, in step S1906.

The lighting control device may generate color pattern values, e.g.,lighting control color sense data, according to the color sense patternselected at step S1906, in step S1908, and may transmit a control signalcontaining the generated lighting control color sense data to acorresponding lighting apparatus through the RF transmission unit, instep S1910.

The corresponding lighting apparatus may extract the lighting controlcolor sense data from the received control signal and control a lightemitting unit based on the extracted lighting control color sense datato output color sense identical or similar to the selected image.

FIG. 20 is a flowchart showing an example of a lighting apparatuscontrol method using a mosaic pattern processing method. The mobiledevice may crop or resize a selected or photographed image, in stepS2002, and set a mosaic interval pixel size, in step S2004. At thistime, the setting performed at step S2004 may be performed withreference to the width of the image, the number of LED elements in thehorizontal direction, the height of the image, and the number of the LEDelements in the vertical direction.

The mobile device may extract RGB values in unit of the pixel size setat step S2004, in step S2006. The mobile device may generate pixelshaving the RGB values extracted at step S2006, in step S2008.

The above process may be performed with respect to each of the pixelsassigned to the cropped or resized image such that the light emittingunit of the flat type lighting corresponding to the respective pixels orthe flat type lighting corresponding to the respective pixels outputsvarious color senses.

FIG. 21 is a flowchart showing an example of a lighting apparatuscontrol method using a gradation pattern processing method. The mobiledevice may generate a mosaic image with respect to a selected orphotographed image in a manner similar to in FIG. 20, in step S2102. Themobile device may select a first color and a second color within a colorrange, in steps S2104 and S2106, respectively, and generate a gradationusing the selected first color and the selected second color, in stepS2108. The mobile device may uniformly apply the generated gradation toeach mosaic image or all mosaic images to control color sense of thelighting apparatus.

In this embodiment, the two colors are selected from the selected colorrange. Alternatively, all colors within the color range may be selected,or at least one color may be used to generate gradation. Such selectionmay be decided based on power consumption or remaining battery power ofa corresponding mobile device.

FIG. 22 is a flowchart showing an example of a lighting apparatuscontrol method using a color percentage pattern processing method. Themobile device may generate a mosaic image in the same manner as in stepS2102 as described above, in step S2202, and calculate percentages of ared color (R), a green color (G), and a blue color (B), in steps S2204,S2206, and S2208, respectively.

The mobile device may compare the calculated percentages of therespective colors, in step S2210, to distinguish a color having thehighest percentage, in step S2212. Subsequently, the mobile device maydeduce a color average of the color having the highest percentage andcontrol the lighting apparatus using the deduced color average of thededuced color, in step S2214.

Meanwhile, in FIGS. 19 to 22, the mobile device may be replaced by alighting apparatus. The pattern processing methods are individually usedas shown in FIGS. 20 to 22. However, two or more of the patternprocessing methods may be combined to control the lighting apparatus.Also, in the above cases, the mosaic image generation step may not berequired, and the above processes may be performed based on points ordots selected by a user.

Meanwhile, the lighting apparatus may individually control therespective light emitting units based on the number of the lightemitting units for color sense control required through the lightingcontrol device. For example, in a case in which color sense is to bereproduced through a plurality of light emitting units, the same colorsense control data may be provided to all of the light emitting unitssuch that each of the light emitting units reproduce the color sense.Alternatively, individually generated color sense data may betransmitted to some or all of the light emitting units in considerationof at least one factor selected from among a plurality of factors,including, for example, the request of the lighting control device, thenumber of the light emitting units used to reproduce color sense, thepositions of the light emitting units, a space in which color sense isreproduced or the attribute of the space, luminous intensity in thecurrent space, such as a room, e.g., indoor luminous intensity, outdoorluminous intensity, or another appropriate factor.

The lighting apparatus may be controlled to provide color sense similarto natural color sense, such as sunrise, sunset, and a glow in the sky,thereby inducing mental stability and comfort of users. Also, it ispossible to easily and conveniently perform lighting control. Accordingto circumstances, an indoor space may be seen as being widened, or a newatmosphere may be naturally produced.

As can be seen from the above description, it is possible to control thelighting apparatus to provide a lighting effect similar to an image,such as an impressive colors of the sky and a glow in the sky. Also, itis possible to easily and similarly express various impressive colorsenses, such as various color senses required by users, through theabove lighting apparatus and the above lighting control method, therebyimproving user's satisfaction and convenience.

As described above, it is possible to conveniently control the lightingapparatus connected to the lighting control device via the network usingthe lighting control device. Also, it is possible to accurately controlthe color temperature, dimming, and color sense as well as power instages or at once through the interface of the lighting control device.In addition, it is possible to greatly improve convenience and productsatisfaction of users through the lighting system including the lightingapparatus and the lighting control device.

Furthermore, the lighting control device may be linked to the lightingapparatus to perform various functions. For example, as previouslydescribed, it is possible for the lighting control device to adjustdimming and color temperature through motion or touch. In addition, itis also possible for the lighting control device to adjust a color sense(color scheme). Meanwhile, in a case in which the color sense iscontrolled, the lighting control device may be linked to a user motionor touch after the color sense is selected such that the dimming or thecolor temperature can be adjusted in the vertical direction or in thehorizontal direction. In conclusion, it is possible to adjust colorsense data through user touch or motion. In addition, it is possible tosimultaneously control dimming or color temperature as well as colorsense data through an additional motion or touch and drag after the usertouch or motion.

Also, when a lighting control application is executed, the lightingcontrol device may output icons of all or some of the lightingapparatuses available from the current position on a screen of thelighting control device (or another digital device connected to thelighting control device), select an icon corresponding to a desired oneof the lighting apparatuses, and freely control dimming, colortemperature, and color sense through the above-mentioned motion andtouch.

As described above, the lighting control device may control poweron/off, color sense, dimming, and color temperature of a desiredlighting apparatus through the lighting control application in realtime. In addition, the above control may be performed according to aprescribed schedule. In this case, the color sense, the dimming, and thecolor temperature may not be directly applied when the lighting controldevice is turned on/off but may be smoothly or gradually controlled whenthe lighting control device is turned on/off. For example, in a case inwhich the lighting control device is turned on/off, dimming, colorsense, and color temperature are controlled. In the morning or when thedifference between the luminous intensity of the lighting apparatus andthe luminous intensity of the surroundings exceeds a predeterminedlevel, the dimming, the color sense, and the color temperature may besmoothly processed to minimize stimulation to the eyes or discomfort tothe user.

Also, if a user selects a specific point or range within an image whencolor sense data are generated by the lighting control device or thecontroller of the lighting apparatus, a GUI regarding color sense datamay be configured to provide RGB percentages of the selected point orrange. In this case, information regarding luminous intensity of thesurroundings, dimming, or color temperature may also be provided, andinformation regarding RGB percentages may be recommended in addition tothe above information. Consequently, it is possible to provide colorsense similar to the color sense of the original image irrespective ofthe difference in background, position, time, and luminous intensitybetween the image and a real place.

Meanwhile, as previously described, the lighting control device mayrecognize touch and drag inputs, and therefore, it is possible tocontrol a range of color sense change or the change of color sense atpixels in an image through the touch and drag inputs. For example, in acase in which, on an image of a cloudy sky, a user touches a sky havinga blue color sense as a point and releases the point to a cloud having awhite color sense through the drag input, the color sense of thelighting apparatus may be continuously changed from the blue color senseto the white color sense. This may be repeated for a time set by theuser or number of times set by the user. Also, the lighting apparatusmay alternately provide the blue color sense and the white color sensein time order or appropriately generate color sense data regarding othercolor senses present between the above color senses to achieve a smoothtransition.

Also, even in a case in which the lighting control device does notselect an image but selects a region of a motion image, it is possiblefor the lighting apparatus to perform color sense control. For example,the lighting control device or the controller of the lighting apparatusmay extract data regarding color sense data of a region selected fromframes constituting the motion image and configure the extracted data ascolor sense data to be reproduced in the lighting apparatus in a manneras previously described. Also, the lighting control device or thecontroller of the lighting apparatus may provide the configured colorsense data to the respective light emitting units based on the runningtime of the motion image or the number of the frames such that a colorsense similar to that in the motion image can be reproduced. Meanwhile,in a case in which the selected region of the motion image includes aplurality of pixels, color sense data may be configured in therespective pixels using at least one selected from the methods shown inFIGS. 19 to 22.

In addition, color sense data of images selected based on certain timeperiods or time zones, such as morning, afternoon, and evening, and/ordays of the week through the lighting control device may be previouslystored, and then color sense data of images may be provided oncorresponding time periods, time zones and/or days of the week.Meanwhile, images used for color sense reproduction are not limited toimages or motion images stored in the lighting control device. Imagesused for color sense reproduction may be received from other digitaldevices or servers connected to the lighting control device.

Meanwhile, the lighting apparatus may store and use favorite color senseconfiguration data for each user. For example, assume that user Aconfigures color sense data using a color sense of sky blue, and user Bconfigures color sense data using a color sense of pink. When user Areturns home, a mobile device, e.g., a lighting control device, of userA may pair with the lighting apparatus such that the lighting apparatuscan be immediately applied. In this case, the lighting control devicemay be previously registered such that the lighting control device canbe used although a lighting control application is not executed in thelighting control device. Meanwhile, in a case in which another persondifferent from user A or user B breaks into the house, or thecorresponding lighting apparatus searches a mobile device of the person,color sense data previously configured to prepare for such a case may bereproduced. As an example of the previously configured color sense data,light containing red indicating warning may be blinked such that user Aor user B can easily recognize such a situation.

Meanwhile, although not shown, in addition to motion or touch of thelighting control device, voice or gesture of a user may be recognizedthrough a camera or speaker included in the lighting control device, aperipheral digital device or other equipment that can be paired with thelighting control device or the lighting apparatus, and which includes asensor or chip capable of transmitting and receiving data. Here, it ispossible to control power on/off, dimming, and color temperature of thelighting apparatus and to reproduce color sense data using the device.For example, a user may input a voice for dimming control through anaudio receiving unit of the lighting control device to control a dimminglevel of the corresponding lighting apparatus.

Alternatively, in a case in which a user takes a predetermined gesturewhile wearing a glove having a module paired with the lighting controldevice such that the module communicates with the lighting controldevice or having a predetermined apparatus paired with the lightingcontrol device so as to communicate with the lighting control device,data regarding the user's gesture may be generated, and the generateddata may be interlocked with lighting control functions to controllighting based on the user's gesture. In addition, the user's gesturerecognized through a camera of the lighting control device may beanalyzed, and the analyzed gesture data may be interlocked with controlfunctions of the lighting apparatus to control the lighting apparatusbased thereupon.
